Abstract (en)

[origin: EP3597613A1] Provided is an interlayer film for laminated glass with which change in partial wedge angle can be suppressed at the time of preparation of laminated glass, and double images can be suppressed in the laminated glass. The interlayer film for laminated glass according to the present invention has one end, and the other end having a larger thickness than the one end; the thickness of the interlayer film does not increase evenly from the one end toward the other end, and an average rate of change in partial wedge angle determined by the following formula (X) is 10% or less when an interlayer film finally pressure-bonded is obtained through a predetermined process using the interlayer film for laminated glass as an interlayer film before pressure-bonding, and each partial wedge angle is measured in each of the interlayer film before pressure-bonding and the interlayer film after final pressure-bonding.finalpressure-bonding.Rateofchangeinpartialwedgeangle%=Partialwedgeangleofinterlayerfilmafterfinalpressure-bonding−Partialwedgeangleofinterlayerfilmbeforepressure-bonding/Partialwedgeangleofinterlayerfilmbeforepressure-bonding×100
